The key to doing it is doing it quick enough that it doesnt connect.

 It's neither a bug, nor it is telnet(1)-specific.  It is happening
 because your terminal key '^\' is bound to a special QUIT character.
 Try `stty quit undef' or `stty -isig' before the telnet(1) session.
 Refer to the stty(1), termios(4) and signal(3) manpages for details.
